Raspberry Pi 5 Graphics Continue with Driver, Crazy Fast Compared to RPi 4

  "This is also now in the Wayland-enabled world where the Wayfire compositor is powering the Raspberry Pi desktop." Wayland on the pi. This is great news!

  OpenGL ES is boring though. I want to know how well does desktop OpenGL on Zink on Vulkan runs.

    I thought their Vulkan driver was doing pretty well but I don't follow it.

      I believe the Pi 4's Vulkan driver only supported Vulkan 1.0. At some point Zink added a requirement that the Pi 4 doesn't support. The specs for the Pi 5 say Vulkan 1.2, but for comparison the open source turnip vulkan drivers for Snapdragon Adreno GPUs supports Vulkan 1.3.

  Will I actually be able to buy one in the U.S. this time around? :(

  In the thread on RPi5's release announcement, I wrote that gpu performance is lagging compared to cpu, ram & storage upgrades on successive RPi models (VC6 being a minor upgrade). Looks like that view may need revisiting... :-) As an aside, I'd be curious how this VideoCore VII compares to gpus found on RISC-V boards like those based on JH7110 and TH1520. From what I've read, those gpus (PowerVR based, iirc) are newish designs with a nice RAM bandwidth preserving architecture. BUT! Implementation (like, process node) matters, and so does driver support. Looks like RPi5 sure has the edge on the driver side! Although (at this time) you probably wouldn't go for a RISC-V board for performance reasons anyway. But it would be nice to see how their gpus compare to the RPi5's in real-world benchmarks.
